Barbed Fitting for K40 Air Assist
thingiverse
I needed a fitting for 1/4" hose that would work with what I have found to be the best air assist design on Thingiverse. Here is the air assist: https://www.thingiverse.com/thing:2421971 So, I wanted something I could glue into the hole for the hose that had a barbed fitting, so I designed my own. It is design so that NO supports are needed at all. Even the ring near the top has a small taper to make sure no filament is hanging out in space. This fitting was tight, and with a little glue has held perfectly. Add some coiled tubing from Walmart or Harbor Freight, and no need for cable tray at all.
